Rolling dynamic compaction (RDC) is a ground improvement technique, which involves towing a non-circular module behind a tractor to achieve soil compaction. When compared against conventional static and vibratory compaction techniques, RDC is capable of compacting thicker layers of soil and at a faster operating speed. This study validates the developed numerical scale model against a field study using the full-size RDC module. Numerical results were compared with the field data in four aspects namely, displacements at the ground surface, and at depths of 0.7 and 1.1 m, pressures at 0.7 and 1.1 m depths, energy delivered by the RDC module into the underlying soil, and the depth of improvement. It is concluded that, numerical results are in good agreement with the field data. This paper also proposes that pressure results are an imperfect indicator to assess the optimum number of RDC passes, whereas, ground settlement is recommended since it better reflects ground improvement due to RDC and it has a clear relationship with the number of passes.

碾压强夯（RDC）是一种地面改良技术，它涉及在拖拉机后面拖曳非圆形模块以实现土壤压实。与传统的静态和振动压实技术相比，RDC 能够以更快的运行速度压实更厚的土壤层。本研究使用全尺寸 RDC 模块根据实地研究验证开发的数值比例模型。从地表位移、0.7和1.1 m深度处的位移、0.7和1.1 m深度处的压力、RDC模块传递到下伏土壤中的能量以及深度4个方面的数值结果与现场数据进行了比较。的改进。得出的结论是，数值结果与现场数据吻合较好。
